EnvoFuel is a process (using the ThermoFuel system) in which
scrap and waste plastics are converted into diesel fuel. The
system uses liquefaction, pyrolysis and the catalytic
breakdown of plastics.
The system can handle a wide variety of plastics that are
currently sent to landfills. A major advantage of the
process is its ability to handle unsorted, unwashed plastic
and its extremely high efficiency.
An EnvoFuel plant can produce up to 9,300 litres of
high-grade diesel fuel from 10 tonnes of waste plastics,
with system modules ranging from 10 to 20 tonnes per day.
Larger systems can be built from these modules. Out
qualifying conventional plastic recycling techniques, this
means that the EnvoFuel system effortlessly processes a
great variety of plastics: heavily contaminated plastics
such as mulch film., agricultural plastics such as silage
wrap, trickle tape and other plastics that are hard to
recycle (e.g. laminates of incompatible polymers, multilayer
films or polymer mixtures).
In fact, most plastics can be processed directly even if
contaminated with dirt, aluminium laminates, printing inks,
oil residues, etc.
Current situation of recycling of plastics
methodologies have been tried and tested to process
waste plastics for many years, with recycling becoming
the most common method reflecting (today’s environmental
requirements). Plastics that cannot be processed are
handled by waste management companies by normal
landfilling or incineration.
years, the building or expanding of gasifiers (most
notably the levels of emissions) has become difficult
due to opposition from governments and community groups
with environmental concerns.
of plastic is a superior method of reusing this
resource. The distillate product is an excellent fuel
and makes EnvoFuel one of the best, economically
feasible and environmentally sensitive recycling systems
in the world today.
diesels can be used in any standard diesel engine,
trucks, buses, trains, boats, heavy equipment and
a process of thermal degradation in the absence of
oxygen. Plastic waste is continuously treated in a
cylindrical chamber and the pyrolytic gases are
condensed in a specially-designed condenser system. This
yields a hydrocarbon distillate comprising straight and
branched chain aliphatics, cyclic aliphatics and
aromatic hydrocarbons. The resulting mixture is
essentially the equivalent to petroleum distillate.
is pyrolised at 370ºC-420ºC and the pyrolysis gases are
condensed in a series of condensers to give a low
sulphur content distillate. The de-sulphur unit makes
the process complete and turns the fuel into a
essential steps in the pyrolysis of plastics involve:
oxygen from pyrolysis chamber;
heating the plastic to a narrow temperature range
without excessive temperature variations;
gases through a catalytic converter;
carbonaceous char by-product before it acts as a thermal
insulator and lowers the heat transfer to the plastic;
condensation and fractionation of the pyrolysis vapours
to produce fuels of excellent quality and consistency
